The Clinical Significance of Pollen and Fungi Concentrations for Allergic Rhinitis: A Three-Year Study.

Abstract

The relationship between disease severity and exposure to allergensin allergic rhinitis (AR) patientsisnot fully clarified presently.We aimed to detect the correlation between airborne pollen and fungi concentrations in a Mediterranean region with symptomscores. A total of 98 patients suffering from AR rated their symptoms at the time of exacerbation using the Total 5 Symptoms Score (T5SS) and the Visual Analogue Scale (VAS). Patients' quality of life (QoL) was estimated by using either disease-specific (Rhinoconjunctivitis Quality of Life Questionnaire(RQLQ) and mini-RQLQ) or generic (Short-Form 36 (SF-36) and Beck Depression Inventory (BDI)) questionnaires. All patients' responses were correlated with aerobiological data. Skin prick tests (SPTs) were used to detect sensitivities to the most common registered pollen and fungi species. A significant positive correlationbetween total pollen and fungi counts and disease-specific questionnaires was found only for the RQLQ. Accordingly, a significant positive correlation was found between total pollen and fungi counts and T5SS (r = 0.655, p = 0.021), with breathing (r = 0.620, p = 0.032) and sneezing (r = 0.660, p = 0.020) being strongly affected. Moreover, a tendency towarda higher VAS score was found as total pollen and fungi counts increased (r = 0.523, p = 0.081). We found a significant correlation between patients' symptoms and pollen and fungal air concentrations. Our results emphasize the clinical significance of pollen and fungi maps in everyday clinical practice.
